Embodiment Construction

[0012] As shown in the drawings, the caisson sinker floating island of the present invention includes an upper floating circle 4 and a lower floating circle 6, and the two floating circles are connected together by a rigid connecting rod 3. A buoy 2 is arranged between the two buoys, and the outside between the upper buoy 4 and the buoy 2 and the outside between the lower buoy 6 and the buoy 2 are all surrounded by waste fishing nets 7. For firmness, the fishing nets can be tied up. Aquatic plants 5 are bound on the upper floating ring 4 . The bottom of the lower floating ring 6 is surrounded by waste fishing nets and soft materials 1, such as plastic ropes and hemp ropes, are suspended on the waste fishing nets.

[0013] When in use, the floating island is directly thrown into the water body to be treated, and a biofilm will be formed on the wrapped waste fishing net and the soft material 1 suspended on the lower floating ring 6 to carry out self-purification treatment on the...

Abstract

The invention provides a tandem water body in-situ bioremediation caisson floating island which comprises an upper water wing and a lower water wing. The two water wings are connected together by a rigid connecting rod; a can buoy is arranged between the two water wings; the outside between the two water wings and the can buoy is muffled by a fishnet; an aquatic plant is bound on the upper water wing; and the bottom of the lower water wing is muffled by the fishnet and a soft material is hung on the fishnet. When being applied, the whole caisson floating island is put into the polluted water body and floats on the water surface due to the effect of the can buoy. A biomembrane is formed on the waste fishnet between the two water wings and the can buoy and on the soft material hung on the lower water wing, which carries out self-purification treatment to the water body. Simultaneously, the aquatic plant bound on the upper water wing not only beautifies the environment, but also has sorption to the eutrophic substance in the water body. The caisson floating island is characterized by simple structure, floating fluidity, no need of civil engineering construction, low investment, low cost, good treatment effect and the function of beautifying environment simultaneously.

Description

technical field [0001] The invention relates to a device for purifying water bodies, which belongs to the technical field of purifying polluted water bodies. Background technique [0002] It is a common method to purify polluted water by biofilm method. Generally, a dynamic membrane reactor is placed in the water body or a soft material is suspended to produce a biofilm. The structure of the dynamic membrane reactor is complex. The cost is high, and soft materials are easy to kink together, which affects the amount of biofilm. [0003] Chinese patent CN2856033 discloses "a biological grid for sewage treatment", which includes a metal mesh plate and fiber bundles, and the fiber bundles are fixedly connected to one side of the metal mesh plate. The fiber bundles are fixedly connected on both sides of the metal mesh panel. Fiber bundles can be braided into bundles of Nylon, Velen, Acrylic or Polyester. When in use, insert the stencil into the sewage outlet or fix it in the ...
